Specification. of Letters Patent. Application filed November 23, 1910. Serial No. 593,943.

LOGKING. SLIlP-GIJOSURE FOR VESSELS.

PatentedMay21,1912.

Be it known that I, GEORGE W. BEADLE, a citizen of the United States,- residing at Montclair, in the county .of Essex and State of New Jersey, have invented certain new and useful Improvements in Looking Slip- Closures for Vessels, of "which the following is 'a specification.

This invention relates to locking slip closures for vessels and has for its object to produce a closure of this nature which will be simple in construction and efficient in. action.

To these ends the invention consists in the novel details of construction and combinations of parts morefully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawingsforming a part. of this specification in which like numerals refer to like parts in all of the views,-Figu're 1 is a long1tudinal sectional,

view of a vessel provided with a closure made in accordance with my invention.

Fig. 2 is asectional view on the line 22, of

theparts shown in Fig. 1 Fig. 3 is a view similar 'to Fig. 1, illustrating a slightly modified form of closure. view of the closure shown in Fig. 3. Fig. 5 is an enlarged detail sectional view of 'a 1 portion of the closure illustrated in Figs. 3

and 4. j v

1, indicates anysuitable body portion, 2 a bottom closure therefor, and 3 a cap 010-- sure for the top portion of the body 1. To the slip closure 3 is secured by any suitable means as by a staple 4, or by adhesives a locking disk 5. This disk 5 is preferably made slightly larger than the interior of the vessel proper; and then can only be inserted inside said vessel as shown by slightly dishing or flexing the disk. When flexed or dished disks suchas '5 are employed in connection with very thin body portlons 1, and especially when said dished disks 5 are considerably larger than said body-portions 1, the said body portions will upon handling be distorted into a more or lesspval form, unless some means, such as the flange 6 of a cover is employed to prevent this distortion. 1 Furthermore when this distortion is allowed to take place, the 'hold or biting action 'of' the locking disk or plate 5 is extend only parti'all Fig. 4 is a plan largely lost. It is therefore an important feature of my invention to provide a bracing flange 6 in connection with my locking disk or plate 5, in order to prevent the vessel body from being distored when subjected tothe pressure of handling and to thereby cause a tighterlocking action between the vessel body and the disk or plate 5.

- After the parts are forced into theposition shown in Fig. 1, it is evident the disk 5 will frictionally hold the cover in place, and if it is somewhat larger than the interior' of the vessel, said cover 3 cannot be removed except by a turning or a screwmg act-ion; and that therefore slip covers such as 3, may be. firmly and readily locked to thin walled vessels such as those usually made of paper stock. Since the 'turning action may be considerable in locking closures of this nature, I sometimes provide the cover 3 with semicircular slots 10 which through the said cover, as best indicate in Figs. 3 and 5, and I pass a staple 11 through the slots in said cover and through said locking disk or plate 5 as plainly shown. in Figs. 3, 4 and 5..

With such a structure a turning action uponthe closure=3 will cause the thinner webs 12 of the said closure to be torn or cut bythe staple 11, and thereby disclose the fact that the vessel has been opened. If a great deal of force is re uiredto'open the vessel, thesaid slots 10'w1ll be ripped to theirextremities before the closure is rein'oved, while if a slight force is required, the, slots will .only

-be,torn throughout a portion of their length.

It is obvious that those skilled in the art may yary the details of construction and arrangement of parts without departing from the spirit of my inventionand therefore I do not wish to.be limited to such features except as may be required by the claims.

1. The combination of a vessel having flexible resilient walls; and a closure comprisin a. cover portion having a flanged rim a apt'ed to tightly fit the-outsideof the wall of the vessel, and a dished diskportion secured to said cover portion adapted to fit the interior of said vessel, said flanged rim extending along the said outside wall below the point engaged by said disk, substantially as described.

2. A vessel closure comprising a flanged In'testimony whereof I afiix my signature cover portion having grooves therein and in presence of twowitnesses. adapted to fit the outside of said vessel; a

dished disk portion adapted to fit the inside GEORGE B 5 of said Vessel; and fastening means passing Witnesses: I
